You’ve probably heard people who work late night shifts in hospitals, fire stations, restaurants, or on the road protecting our streets talk about how light during the day has a negative impact on their ability to get a decent amount of restful sleep. But, did you know there is a real reason behind it? It’s not merely a preference for darkness that’s robbing them of the recuperative sleep they need in order to wake up refreshed and ready to face the day. But why does light have such a profound impact on sleep and what can people who work these necessary late shifts do to get the kind of sleep they need?

Why Does Light Negatively Impact Sleep?

“In the presence of light, your brain will not produce melatonin,” says Dr. Michael Breus, PhD, Sleep Specialist: On the surface that doesn’t seem like such a profoundly negative thing. However, melatonin is one of the vital hormones that plays a significant role in helping people not only fall asleep but also to remain asleep throughout the night. If a room has too much light, that makes things much more difficult for anyone looking to get a proper amount of sleep.

Human beings are built to respond to the natural light and dark cycle of the day. It makes sense that we would have evolved this way. After all, unlike cats, our eyes aren’t equipped to see very well in the dark. So, we had to do our hunting in the daytime and, the earlier we started looking for food, the more food we’d find before the day was over. As a consequence, our brains are more alert during daytime hours. As the sun sets, we start to slow down. Even if you consider yourself a night person, your productivity still wanes with the loss of daylight. Of course, nowadays we are surrounded by artificial light. It makes sense that this light might wreak some havoc on our sleep/wake patterns.

Every Plushbeds latex mattress, latex topper and memory foam mattress is sold with a carbon neutral mindset.

What this means that we have obtained an offset to balance out any greenhouse gas emissions we create by running our website and back end operations.
We worked with TerraPass on doing an audit. They helped us measure exactly how much carbon we were putting into the atmosphere by running the Plushbeds website.

Armed with that knowledge, TerraPass has taken actions to offset our carbon footprint by funding clean energy and other projects that reduce greenhouse gas emissions.
At the end of the day our emissions will be balanced out by a comparable amount of reductions.

Every TerraPass project is conducted and verified according to a publically available carbon offset standard such as the Voluntary Carbon Standard 2007 and the Climate Action Reserve.

We hope that in time many more websites will also become carbon neutral.
